Have you ever felt tingling in your toes, numbness in your fingers, or a burning sensation in your feet without knowing why?
These sensations can sometimes be signs of neuropathy, a condition involving damage or dysfunction of the nerves.
Neuropathy can affect how you feel touch, move your muscles, or perform everyday activities. Some people experience mild symptoms, while others develop persistent discomfort, weakness, or balance difficulties.
But neuropathy is not one single disease, and the cause is not always obvious.
Understanding what neuropathy is, why it happens, and which symptoms deserve attention can help you take the right next steps.
What Is Neuropathy?
Neuropathy is a broad term describing damage or dysfunction affecting nerves.
When people use the term, they are often referring to peripheral neuropathy, which affects nerves outside the brain and spinal cord.
These nerves carry information between your central nervous system and the rest of your body.
They help you:
- Feel temperature, pressure, and pain
- Move your muscles
- Maintain balance and coordination
- Regulate certain automatic body functions
When peripheral nerves become damaged, the signals they carry may be disrupted.
This can cause unusual sensations, reduced feeling, weakness, or other symptoms.
Neuropathy may affect one nerve, several individual nerves, or many nerves throughout the body.
What Causes Neuropathy?
Neuropathy can develop for several reasons. Identifying the cause matters because treatment often depends on the underlying condition.
1. Diabetes
Diabetes is one of the most common causes of peripheral neuropathy.
Over time, elevated blood glucose and other metabolic changes can damage nerves and the small blood vessels that supply them.
Diabetic peripheral neuropathy often begins in the feet and may gradually affect the legs or hands.
Symptoms can include numbness, tingling, burning pain, and reduced sensation.
2. Vitamin Deficiencies
Certain vitamins are essential for healthy nerve function.
A deficiency in vitamin B12, for example, can cause neurological symptoms, including numbness, tingling, and balance difficulties.
Other nutritional deficiencies may also contribute to nerve problems.
Importantly, excessive vitamin B6 supplementation can itself cause neuropathy.
Testing and treatment should be guided by a healthcare professional rather than taking high-dose supplements without knowing the cause.
3. Nerve Injuries or Compression
Physical injuries or pressure on a nerve can interfere with normal nerve function.
Examples include:
- Carpal tunnel syndrome
- Nerve injuries following trauma
- Certain repetitive compression injuries
- Nerve entrapment around joints
A compressed nerve may cause symptoms in a specific area rather than the more widespread pattern seen in some forms of peripheral neuropathy.
4. Alcohol-Related Nerve Damage
Long-term heavy alcohol use can contribute to peripheral neuropathy.
This may involve direct toxic effects and nutritional deficiencies.
Symptoms commonly develop gradually and may include burning, numbness, or weakness in the feet and legs.
5. Autoimmune and Inflammatory Conditions
Some autoimmune disorders can damage peripheral nerves.
These conditions involve the immune system mistakenly attacking parts of the body’s own tissues.
Examples include certain inflammatory neuropathies and neuropathy associated with systemic autoimmune diseases.
The diagnosis may require specialist assessment and additional testing.
6. Medications and Medical Treatments
Certain medications, including some chemotherapy drugs, can cause peripheral nerve damage.
This is sometimes called medication-induced or chemotherapy-induced peripheral neuropathy.
Symptoms may appear during treatment or persist afterward.
Do not stop prescribed medication without discussing your symptoms with the prescribing clinician.
7. Kidney, Thyroid, and Other Medical Conditions
Chronic kidney disease, thyroid disorders, infections, and certain other medical conditions can contribute to neuropathy.
In some cases, a person has several contributing factors.
8. Hereditary or Unknown Causes
Some forms of neuropathy are inherited.
In other cases, testing does not identify a specific cause. This is known as idiopathic neuropathy.
Even when the cause remains unclear, symptom management and monitoring may still help protect function and quality of life.
What Are the Early Signs of Neuropathy?
Early neuropathy symptoms may be subtle.
You might first notice that your toes feel slightly numb, your feet tingle at night, or certain sensations feel different than they used to.
Common symptoms include:
Tingling or Pins and Needles
A prickling, buzzing, or crawling sensation may develop in the feet, hands, or other affected areas.
Numbness
You may have difficulty feeling pressure, temperature, or minor injuries.
Reduced sensation in the feet is especially important because cuts or sores may go unnoticed.
Burning or Electric-Like Pain
Some people describe neuropathic pain as burning, shooting, stabbing, or resembling an electric shock.
Symptoms may become more noticeable at night.
Sensitivity to Touch
Even light contact from socks, clothing, or bedsheets may feel uncomfortable or painful.
Muscle Weakness
When motor nerves are affected, you may notice reduced strength, difficulty lifting part of the foot, or problems with fine hand movements.
Balance Problems
Reduced sensation in the feet can make it harder to sense your position while standing or walking.
This may increase the risk of stumbling or falling.
Not everyone with neuropathy experiences pain. Some people mainly notice numbness or reduced sensation.
Where Does Neuropathy Usually Start?
Many common forms of peripheral neuropathy begin in the feet.
Symptoms may first affect the toes and gradually spread upward.
This is sometimes called a stocking-glove pattern because symptoms can eventually affect areas covered by stockings or gloves.
However, not all neuropathy follows this pattern.
Some forms affect a single nerve, one side of the body, or particular muscle groups.
The location and progression of symptoms can help healthcare professionals investigate the possible cause.
What Is Often Mistaken for Neuropathy?
Several conditions can cause symptoms that resemble peripheral neuropathy.
These include:
- Sciatica: Can cause pain, tingling, or numbness travelling into one leg.
- Carpal tunnel syndrome: Causes symptoms in areas of the hand supplied by the median nerve.
- Poor circulation: May cause coldness, colour changes, discomfort, or other symptoms in the limbs.
- Plantar fasciitis: Commonly causes heel pain, particularly with the first steps after rest.
- Certain joint or muscle conditions: May cause discomfort that is mistaken for nerve pain.
These conditions are not necessarily interchangeable.
For example, sciatica usually involves irritation of spinal nerve roots, while common distal peripheral polyneuropathy affects nerves farther from the spinal cord.
Read more about sciatica and plantar fasciitis if your symptoms resemble those conditions.
How Is Neuropathy Diagnosed?
A healthcare professional will usually begin with your medical history and a neurological examination.
They may ask:
- When did your symptoms begin?
- Which parts of your body are affected?
- Do you experience numbness, tingling, pain, or weakness?
- Have you been diagnosed with diabetes or another medical condition?
- Are you taking medications that can affect nerve function?
- Do you have a family history of neurological problems?
The examination may assess sensation, reflexes, muscle strength, balance, and coordination.
Depending on the findings, additional tests may include:
- Blood tests, such as glucose or HbA1c and vitamin B12
- Thyroid or kidney function testing
- Nerve conduction studies
- Electromyography (EMG)
- Other tests when a specific cause is suspected
Not every patient needs every test.
The goal is to identify potentially treatable causes and understand which nerves are affected.
What Is the Neuropathy Disability Score?
The Neuropathy Disability Score (NDS) is a clinical assessment tool used in some settings to evaluate signs of peripheral neuropathy.
It commonly considers findings such as ankle reflexes and sensory responses to vibration, temperature, or pinprick testing.
The score can help clinicians assess neuropathy-related impairment, particularly in diabetes care.
However, it does not identify the cause of neuropathy on its own, and it is not a replacement for a full medical assessment.
What Happens If Neuropathy Is Left Untreated?
The outcome depends on the cause, severity, and type of nerve damage.
Some neuropathies remain relatively stable, while others gradually progress.
Possible complications include:
- Increasing numbness or discomfort
- Reduced balance and a higher risk of falls
- Muscle weakness
- Difficulty walking or performing daily activities
- Unnoticed injuries, particularly on the feet
- Foot ulcers in people with significant sensory loss
Not every case of neuropathy gets worse.
However, identifying a treatable cause early may help prevent additional nerve damage.

What Are the Treatment Options for Neuropathy?
Neuropathy treatment depends on the underlying cause and the symptoms affecting your daily life.
Managing the Underlying Condition
If neuropathy is related to diabetes, improving glucose management and addressing other risk factors may help reduce further nerve damage.
If a vitamin deficiency, thyroid disorder, or medication is responsible, treatment may focus on correcting or managing that problem.
Medication for Nerve Pain
Certain prescription medications can help manage neuropathic pain.
Options may include medications such as duloxetine, gabapentin, or pregabalin, depending on the diagnosis and individual circumstances.
These medicines do not necessarily repair damaged nerves, but they may help reduce discomfort.
A prescribing clinician should explain the potential benefits and side effects.
Exercise and Rehabilitation
Appropriate physical activity may help maintain strength, balance, mobility, and general health.
People with significant numbness or weakness may benefit from a personalised rehabilitation programme.
Foot Care and Injury Prevention
If you have reduced sensation in your feet, regular skin checks and suitable footwear are important.
People with diabetes-related neuropathy may need ongoing foot examinations to reduce the risk of ulcers and other complications.
Supportive Musculoskeletal Care
Some people with neuropathy also experience joint stiffness, muscular discomfort, or movement limitations.
Supportive musculoskeletal care may help address these separate issues.
However, spinal adjustments have not been established as a treatment that reverses common causes of peripheral neuropathy, such as diabetic or chemotherapy-related nerve damage.
The underlying neurological condition should be medically assessed and managed appropriately.
Can Neuropathy Be Prevented?
Not every type of neuropathy can be prevented.
However, certain steps may help reduce the risk of some forms of nerve damage.
These include:
- Managing diabetes and other chronic medical conditions
- Eating a balanced diet
- Avoiding excessive alcohol consumption
- Reviewing medication-related symptoms with your clinician
- Avoiding unnecessary high-dose vitamin supplements
- Seeking assessment for persistent numbness or weakness
- Protecting feet with reduced sensation from injury
Early recognition is particularly important when symptoms are related to a treatable medical condition.
When Should You See a Doctor for Neuropathy Symptoms?
Arrange a medical evaluation if you notice:
- Persistent tingling or numbness
- Burning pain in your feet or hands
- Gradually increasing weakness
- Balance problems or repeated falls
- Reduced sensation that affects daily activities
- New foot wounds you cannot easily feel
Seek emergency medical care for sudden one-sided weakness or numbness, facial drooping, difficulty speaking, or other possible stroke symptoms.
Rapidly progressing weakness, breathing difficulties, or severe new neurological symptoms also require urgent medical attention.
Do not assume these symptoms are simply part of peripheral neuropathy.

Frequently Asked Questions
1. What is the most common cause of peripheral neuropathy?
Diabetes is one of the most common identifiable causes of peripheral neuropathy. Other causes include nutritional deficiencies, alcohol-related damage, medications, autoimmune conditions, and inherited disorders.
2. Can neuropathy cause symptoms without pain?
Yes. Some people mainly experience numbness, reduced temperature sensation, weakness, or balance problems rather than pain.
3. Is neuropathy always permanent?
No. Some types improve when the underlying cause is treated, while others may cause lasting nerve damage. Recovery depends on the cause, severity, and duration of the condition.
4. Can neuropathy affect only one foot or hand?
Yes. Neuropathy involving a single nerve can affect one area. However, new one-sided symptoms may have other causes and should be assessed, particularly if they develop suddenly.
5. What is the difference between neuropathy and nerve compression?
Neuropathy is a broad term for nerve damage or dysfunction. Nerve compression is one possible cause of nerve symptoms, often affecting a particular nerve or nerve root. Many common forms of peripheral neuropathy are caused by metabolic, nutritional, toxic, or other medical conditions rather than spinal compression.
